F3000.0040-F 3000.1000 FIXATIVES 211 



3000.0040 Apathy and Boeke test. 1910b Spuler Ehrlich, Krause, et al. 1910, 2 :524 



formula: water 240, inercurit,' chloride 25, nitric acid 10 



3000.0040 Frenzel 1886 1780, 26 :232 



formula: 80% ale. 125, sat. sol. mercuric chloride in 80% ale. 125, nitric acid 10 

 note: Mercuric chloride is about 20% soluble in 80% ale.; the 125 parts quoted above 

 therefore contain about 25 of the dry salt. 



3000.0040 Kostanecki and Siedlecki 1896 1780, 48:184 



formula: water 250, mercuric chloride 9, nitric acid 7.5 



3000.0040 Saling 1906 test. 1937 Gatenby and Painter Gatenby and Painter 1937, 389 

 formula: water 125, 957o ale. 100, mercuric chloride 5, nitric acid 10 



3000.0060 Mercuric-hydrochloric 



3000.0060 Meyer 1912 test. 1915 ips. Meyer 1915, 198 



formula: 95% ale. 250, mercuric chloride 12.5, hydrochloric acid 1 



3000.1000 Mercuric-formaldehyde 



These are very bad fixatives, save for a few specialized purposes for which some have been 

 recommended by their inventors.

3000.1000 Carleton and Leach 1938 Carleton and Leach 1938, 33

3000.1000 Downey 1913 8545, 15:25 



formula: water 225, mercuric chloride 20, 40% formaldehyde 25, sodium chloride 2.2 



3000.1000 Eltringham 1930 fixative A — auct. Eltringham 1930, 44 



formula: water 225, mercuric chloride 15, 40% formaldehyde 25 

 recommended for: soft parts of insects free of chitin.

3000.1000 Heidenhain 1916a Heidenhain's weak mixture — compl. script. 



23632, 32 :365 

 formula: water 200, mercuric chloride 10, 40% formaldehyde 50, sodium chloride 1.25 



3000.1000 Heidenhain 1916b Heidenhain's strong mixture — compl. script. 



23632, 32 :365 

 formula: water 125, mercuric chloride 10, 40% formaldehyde 125, sodium chloride 1.25 



3000.1000 "J.A." test. 1937 Findlay 11360, 57:294 



formula: water 225, mercuric chloride 6.25, 40% formaldehyde 25 



3000.1000 Rosenthal 1900 test. 1907 Bohm and Oppel Bohm and Oppel 1907, 202 

 formula: sat. sol. picric acid 250, 40 7o formaldehyde 12.5 

 use: fixation of adipose tissues before DS 22.4 techniques. 



3000.1000 Schmorl 1928 Schmorl 1928, 29 



formula: water 200, mercuric chloride 11.25, sodium chloride 1.25, 40% formaldehyde 

 50 



3000.1 01 Mercuric-formnldeh^jde-aceiic 



These are slightly better than the preceding class, but they are not nearly as good as 

 straight mercuric-acetic mixtures. There seems to be no reason for the inclusion of the 

 formaldehyde in a general formula of this nature.
